Document Type and Number:
WIPO Patent Application WO/2024/048740
Kind Code:
A1
Abstract:
Provided is a polyimide film which achieves a balance in the properties of chemical resistance, Young's modulus, YI (yellowness), and glass transition temperature when curing is carried out at a temperature of not lower than 430°C, and which is applicable to a display process for LTPS (low-temperature polysilicon) displays, LTPO (low-temperature polycrystalline oxide) displays, and the like. Also provided are, for example, a resin composition and a laminate for forming the polyimide film. The present invention comprises a resin including a structural unit represented by general formula (1) and/or a structural unit represented by general formula (2), wherein the resin is a block copolymer including a first block and a second block, the first block includes a structural unit derived from a compound represented by general formula (4), and the second block includes a structural unit derived from at least one compound selected from compounds represented by general formulae (6) and (7).
